read

public int read()

Read a byte from the stream buffer. Blocks if none available.

Returns:

byte read, or -1 on error (if stream is closed or interrupt).

read

public int read(byte[] buf)

Read a byte buffer from the stream buffer. Blocks if no data available. May return less data than the buffer size.

Returns:

number of bytes read, or -1 on error (if stream is closed or interrupt).

readAvailable

public byte[] readAvailable()

Reads all available data from the stream buffer. Blocks if no data available.

Returns:

bytes array on success, null on failure (if stream is closed or interrupt).

readLine

public java.lang.String readLine()

Reads a line of text from the stream buffer. Blocks if no data available.

Returns:

text string on success, null on failure (if stream is closed or interrupt).

available

public int available()

Get the number of bytes available in stream to read.

Returns:

number of bytes available, -1 on error (if stream is closed).

close

public void close()

Specified by:

close in interface java.io.Closeable

Specified by:

close in interface java.lang.AutoCloseable

Overrides:

close in class java.io.OutputStream
